Newton's Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What happens to an object in motion when no external forces act on it?

Back

It will continue to move at the same speed and in the same direction.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Can you give an example of Newton's Third Law?

Back

When you push against a wall, the wall pushes back with equal force.

Front

What is the relationship between force, mass, and acceleration?

Back

If the mass increases and the force remains constant, the acceleration decreases.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.
